Lumsden McCormick, CPA

What Lumsden McCormick, CPA does

Lumsden McCormick, CPA is a privately held accounting and advisory firm headquartered in Buffalo, New York, founded in 1952. The firm provides strategic planning, business valuation, and forensic auditing services, indicating a practice orientation toward higher-value advisory and litigation-support work rather than commodity tax preparation or basic compliance. With 101-250 employees, the firm operates in the mid-market regional CPA segment, serving clients whose needs cross standard accounting into specialized valuation and forensic engagements.

The firm is led by Sara M Dayton as Managing Partner, representing the current professional leadership of a practice that has operated continuously for over 70 years under a single brand. The firm's business model follows the standard professional services economics of CPA firms: time-and-materials or fixed-fee billing against engagement scopes, with revenue tied to billable hours, headcount, and realized billing rates. The valuation and forensic service mix typically commands premium rates relative to general audit work, supporting a higher revenue-per-employee ratio than peer firms focused solely on tax and compliance.

The available source data is notably thin: the firm's website (lumsdencpa.com) returned only a verification/loading page during data collection, and most enrichment fields (revenue, customer segments, technology stack, partnerships, geographic markets, leadership beyond the named managing partner) are empty. This data gap itself is a material observation for diligence purposes, as it limits visibility into the firm's commercial positioning, client concentration, and growth signals.
